Prolem : Does the length of the string, weight on the of the string, or the angle or the angle of the drop effect a pendulums range in swings the most in 15 seconds? The answer is the longer it is the less times it goes back and forth. So we did 3 test on each length of string and saw how many times it went back and forth and we used ten strings (10cm, 20cm, 30cm, 40cm, 50cm, 60cm, 70cm, 80cm, 90cm, 100cm, ). The highest average was 17 and the lowest was 7. I started to notice that the longer the the less it goes back and forth. I think the longer the string the momentum so it takes longer to get there. i belive the shorter the faster it gets there I feel the expieriment went right because there was 3 test and alost all of them were the same. jbggi
